REFER Source Routing Configuration

To enable realm-based REFER method call transfer:

1. In Superuser mode, type configure terminal and press Enter.

   ORACLE# configure terminal
   ORACLE(configure)#

2. Type media-manager and press Enter.

   ORACLE(configure)# media-manager
   ORACLE(media-manager)#

3. Type realm-config and press Enter.

   ORACLE(media-manager)# realm-config
   ORACLE(realm-config)#

4. refer-call-transfer — Retain the default (disabled) to proxy all REFERs to the next hop. Use enabled to terminate all REFERs and issue a new INVITE. Use dynamic to specify REFER handling on a call-by-call basis, as determined by the value of the dyn-refer-term parameter.
5. dyn-refer-term (meaningful only when refer-call-transfer is set to dynamic) — Retain the default (disabled) to terminate the REFER and issue a new INVITE. Use enabled to proxy the REFER to the next hop.
6. Save and activate your configuration.

   To enable session-agent-based REFER method call transfer:

7. In Superuser mode, type configure terminal and press Enter.

   ORACLE# configure terminal
   ORACLE(configure)#

8. Type session-router and press Enter.

   ORACLE(configure)# session-router
   ORACLE(session-router)#

9. Type session-agent and press Enter.

   ORACLE(media-manager)# session-agent
   ORACLE(session-agent)#

10. refer-call-transfer — Retain the default (disabled) to proxy all REFERs to the next hop. Use enabled to terminate all REFERs and issue a new INVITE. Use dynamic to specify REFER handling on a call-by-call basis, as determined by the value of the dyn-refer-term parameter.
11. Save and activate your configuration.

    To specify policy lookup for a newly generated INVITE:

12. In Superuser mode, type configure terminal and press Enter.

    ORACLE# configure terminal
    ORACLE(configure)#

13. Type session-router and press Enter.

    ORACLE(configure)# session-router
    ORACLE(session-router)#

14. Type sip-config and press Enter.

    ORACLE(configure)# sip-config
    ORACLE(sip-config)#

15. refer-src-routing — Retain the default (disabled) to perform a policy lookup based upon the source realm of the calling party (the issuer of the original INVITE). Use enabled to perform a policy lookup based upon the source realm of the referring party (the issuer of the REFER).
16. Save and activate your configuration.
